Is Ellen DeGeneres' Marriage in Trouble? Portia De Rossi Leaves Oscars Host at Home

American talk show host and comedian Ellen DeGeneres and Portia De Rossi are facing divorce rumours once again.

According to Showbiz Spy, the Ally McBeal star left DeGeneres at home on 29 April, so she could attend the 2014 AOL Digital NewFronts Presentation at the Duggal Greenhouse in Brooklyn, New York.

The Oscar host has been married to the Australian-American actress for the last six years. However, there have been several reports since 2013 that the couple's marriage is on shaky grounds.

According to another report, Rossi told DeGeneres that she wanted the two to spend more time together.

"Portia is very demanding," a source said. "She wants Ellen to work less, and spend more time with her. But Ellen doesn't want to — she has worked hard to get to where she is, and isn't going to let things slide. They both have expensive tastes, and Ellen has to work hard so they can afford them!"

"Ellen and Gillian have been close friends for years and set tongues wagging when they were caught sharing a steamy lip lock in 2000," an insider said. "Ellen has always had a major crush on Gillian, but she's sworn up and down to Portia nothing happened between them. But Portia doesn't believe her. Ellen and Gillian adore each other. Portia's not too happy about it and wants them to stop communicating. She's afraid Ellen will be tempted to stray, even though the funnygal insists that would never happen."

However, DeGeneres told the People Magazine: "I love her [Portia De Rossi] so much it kills me. The tabloids had a photo of Portia not wearing her wedding ring. It is because it gives her blister while riding horses," she said.
